Kristaps Porzingis is expected to get his first NBA experience in the Las Vegas Summer League, headlining a roster that features several players who will be on the Knicks' team in the fall.

Porzingis experienced hip tightness that cut short his last workout with the Knicks just days before the draft. The Knicks used the No. 4 selection on the 7-1 Porzingis last month.

It's unclear yet whether Porzingis will play in Saturday's summer league opener against San Antonio. But the Knicks hope he will be ready for the first game, and expect him to play at some point in Las Vegas.

Derek Fisher will coach the team.

Joining Porzingis on the roster will be No. 19 pick Jerian Grant, Langston Galloway, Cleanthony Early, Ricky Ledo, Travis Wear and last year's second-round picks Thanasis Antetokounmpo, who spent last season in the D-League for the Westchester Knicks, and French big man Louis Labeyrie.

Galloway, Early, Ledo and Wear all played for the Knicks last season. Among them, only Early has a guaranteed contract for the upcoming season. Galloway's is partially guaranteed, but he's in the Knicks' plans and all but assured to be on the 15-man roster.

After signing or acquiring Robin Lopez, Arron Afflalo, Derrick Williams and Kyle O'Quinn in free agency, the Knicks still have four roster spots to fill. Ledo, Antetokounmpo and Wear hope to stick around.

But the Knicks have the $2.8-million room exception and minimum salaries to offer in free agency. They would like to bring back veterans, including Lance Thomas and Lou Amundson, and have expressed interest in guard Willie Green.

Free-agent deals can be signed and announced beginning Thursday.Filling out the summer league team are ex-Cavs center Alex Kirk, guard Jimmy Baron, who played in Turkey, Lithuanian center Ovidijus Galdikas, former Ohio forward Maurice Ndour and Westchester Knicks center Ben Strong.Orlando bound. Jason Smith won't be back with the Knicks. His agency announced on Twitter that Smith had agreed to terms with the Magic.

Smith reportedly agreed to a one-year, $4.5-million deal. The Knicks wanted to bring back Smith, who averaged 8.0 points and 4.0 rebounds last season. But the most they could offer was the $2.8-million room exception.

"So thankful for the opportunity the Knicks gave me this season truly a world class organization. Thank you New York!" Smith tweeted. "I can't wait to get this new season started as a part of the Orlando Magic. I'm counting the days down. #PureMagic #Hardwork."
